Ericsson and Vodafone Netherlands have deployed the country's first cloud based and fully virtualized Voice over LTE (VoLTE) and Wi Fi calling solution.
Wi-Fi calling enables operator voice services to be provided in more locations, such as indoor environments like basements, by complementing macro network coverage. VoLTE offers fast call set-up times and high-definition (HD) voice quality while facilitating a broader range of IP-based communication capabilities, such as video calling over LTE and multi-device support.
The solution is based on a commercial Network Functions Virtualization (NFV) deployment of Ericsson IP Multimedia Subsystem (IMS) and Ericsson Evolved Packet Core (EPC). The complete cloud-based solution also includes Virtual Network Functions (VNF) for Wi-Fi calling, policy control and application server domain.
Matthias Sauder, Head of Networks, Vodafone Netherlands, says: "Network virtualization brings huge opportunities for efficiency and agility. It will allow us to introduce new services more rapidly to our subscribers. We are very pleased with Ericsson's support in deploying NFV in our network in the Netherlands, which will now enable swift launches of new IP-based communication services for our customers."
The end-to-end VoLTE and Wi-fi calling overlay network includes VNFs for the Ericsson IP Multimedia Subsystem with Ericsson Multimedia Telephony Application Server, Ericsson Call Session Control Function, Ericsson Evolved Packet Core with Ericsson Evolved Packet Gateway, Ericsson Wi-Fi Mobility Gateway and other Ericsson control and authentication functions.
